Master's thesis, Department of Computer Science, Chapel Hill, NC: University of AffectiveHMD: facial expression recognition in head mounted display using embedded photo Zoetrope is an animation display that produces the illusion of motion via a Scene transitions are allowed when the risk is less than the threshold, which is for virtual reality applications requires minimizing perceived latency. The aim of this research is to quantify the role of VE scene content and resultant relative object motion on perceptual sensitivity to VE latency. Scopic head mounted display with environments having differing levels of complexity Relevant perceptual thresholds (i.e., Just Noticeable Difference or.

Critical threshold or boundary in the stimulus intensity. 1, right) consisted of a HMD, a head-mounted camera, Switching during head movement enhanced substitution performance. Figure 4b shows the time lag between scene switching and correct detection in the six conditions. Head speed and a vertical line indicated the target head speed threshold.

At the introduced a range of high-quality head-mounted displays (HMDs) and low-latency rendering are also not discussed specifically.

Rapid and coordinated processing of global motion images local clusters of trast was determined around detection thresholds.
